Figure 13-5: Scatter plot
depicting scaled outputs of mean winter (left panels) and summer (right panels)
temperature and precipitation change over land grid boxes representing Spain (top),
Sweden (middle), and Poland (bottom) from each of seven GCM simulations (GFDL
simulations are not shown because they extend only to 2025). Lines connect four
points for each GCM simulation, each point representing standardized regional
changes in climate from the GCM, linearly scaled according to global warming from
each of the four ACACIA scenarios. The order of points along a line from the origin
is the same for all plots: B1-low, B2-mid, A1-mid, A2-high. Also plotted are 1
and 2 standard deviation limits from 1,400-year HadCM2 unforced simulation, which
is used to indicate natural multi-decadal variability.
